Beit known that we, Sir ARTHUR TREVOR DAWSON, knight, and GEORGE THOMAS BUCK- .HAM, both subjects of the King of Great Britain, residing at Vickers House, Broadway, Westminster, in the county of London, England, have invented certain new and useful Improvements in or Relating to Gun- Mountings, of which the following is a specification.

This invention relates to gun mountings of the casemate or upper deck type in which the elevating and training number or numbers are disposed within a shield moving with the gun in training.

According to this invention we so construct and arrange the-casemate or upper deck mounting that the elevating and training number or numbers can be accommo dated near the gun trunnions between the shield and downward extensions of the carriage cheeks, the space provided beneath the gun by the said extensions serving to receive the rack and pinion of the elevating mechanism so that the necessity for the side bar, which is usually provided in mountings of this kind, is avoided.

In order that the said invention may be clearly understood and readily carried into reflect we will describe the same more fully with reference to the accompanying drawings, in which Figures 1 and 2 are respectively a sectional rear elevatlon and a sectional slde elevation showing one constructional form of the invention in connection with a twin 1 and 2 showing another constructional form of the invention.

In these figures A is the shield, B, B are the carriage side cheeks and B is the center plate, the gun cradles C C being trunnioned in the side cheeks and the center plate. The side cheeks B, B are extended downwardly as aforesaid and they, together with the center plate are connected to or made integral with a ring or plate D which is rotatably supported by means of ball or roller bearings upon a bearing block D carried by the deck as is well understood. The said ring is prevented from rising during the firing of the gun by a circular clip D (orby several separate clips) attached to the bearing block D. The gun cradles are pro- GUN -MOUNTING.

Specification of Letters Patent. Patented luay 28, 1918, Application filed May 26, 1915. Serial No. 30,707.

vided with elevating racks C, C situated stead of racks and pinions any other appropriate gearing may be used. The side cheeks carry seats or platforms 0, c for the I elevating and training numbers respectively who are accommodated between the outer faces of the side cheeks and the shield A in such a position that the eye pieces of the sights can be arranged contiguous to the gun trunnions as shown.

In the construction shown by Figs. 1 and 2 the ring D is of angle cross section and roller and ball bearings are interposed in the usual manner between the bearing block and the vertical and horizontal portions respectively of the ring. If desired the vertical portion of the ring may be extended to. form what may be termed a hollow training pivot.

In the construction shown by Figs. 3 and 4 the plate D carries a bearing (1 which engages with a center pivot d projecting upwardly from the bearing block D as has already been proposed. The said center of downward extensions of said cheeks, gun

elevating means arranged centrally beneath the gun andbetweensaid downward extensions, and a handle arranged between one of the cheeks and the shield for operating said elevating means.

In a gun mounting, the combination with the shield and the gun carriage checks, of downward extensions of said cheeks, a gun elevating rack arranged centrally beneath the gun and between said downward extensions, a pinion gearing with said rack, and a handle arranged between one of the cheeks and the shield for operating said pinion.
